endo stuff Flashcards
Hypothalamic-hypophyseal portal system
Growth Hormone
S: GHRH from hypothalamus
E: growth of muslce and bone
Hypothalamic-hypophyseal portal system
Prolactin
S: PRH from hypothalamus
E: Milk production
Hypothalamic-hypophyseal portal system
TSH
S: TRH from hypothalamus
E: increase TH at thyroid
Hypothalamic-hypophyseal portal system
ACTH
S: CRH from hypothalamus
E: increase cortisol secretion at adrenal gland
Hypothalamic-hypophyseal portal system
FSH and LH
S: GnHR from hypothalamus
E: increase secretion of sex hormones, stimulate gamete production
Thyroid Hormone is
a 2 amine hormone w iodine
exists as T3 or T4
thyroid hormone
S: TSH from anterior pituitary
E: increase cells metabolic rate and effects digestion, thermoregulation, energy levels
What is calcitonin
a peptide secreted by c cells of the thyroid
calcitonin
S: high Ca++ in blood
E: deposit Ca++ in bone
parathyroid glands are prime regulators of
blood calcium
parathyroid glands are located on
the back of the thyroid
parathyroid hormone PTH
S: low blood ca++
E: cause bone to free up Ca++ from bone and put it into blood
minerlacorticoids, mostly aldosterone
S: angiotestin 2 (a hormone) and other factors
E: increase sodium retention by kidneys
glucocorticoids such as cortisol
S: ACTH from the anterior pituitary
E: long term stress response including increased blood glucose
epinepherine and norepi
S: sympathetic neuron firing
E: short term stress response, including increased HR, BMR, and BG
Melatonin
S;hypothalamus neuron firing
E: sleepiness
glucagon
S: low blood sugar
E: raise blood sugar by causing the liver to convert glycogen into lots of glucose
insulin
S: high blood sugar
E: lower blood sugar by increasing glucose absorption in many tissues and causing liver to build glycogen from many glucose molecules
estrogen
S: FSH from anterior pituitary
E: female reproduction functions
progesterone
S: LH from anterior pituitary
E: female repro functions
testosterone
S: LH from anterior pituitary
E: male repro functions
Posterior pituitary stores these hormones that are made in the hypothalamus
oxytocin and ADH
Oxytocin
S: hypothalamic neuron firing
E: uterine contraction, lactation, bonding
ADH
S: hypothalamic neuron firing
E: vasopressin- kidneys conserve water (less urine), blood vessel contraction
